1990～1993年,湖南零陵地区水产站承担了湖南省科学技术委员会下达的“稻鱼高产模式研究”科研项目。经四年的反复实践研究,确立了“田凼结合养鱼”这一稻鱼高产模式。四年共实施4328亩,产鱼363.35吨,产稻谷4055.43吨。其中1993年实施面积1150.8亩,产鱼157.2炖,亩平136.6kg;产稻谷1039.98吨,亩平903.7kg。稻鱼总产值201.1万元,亩平1747.48元,纯收入129.42万元,亩平1124.60元,投产比1:2.81。1993年底已通过省级技术鉴定。现将稻鱼高产模式的主要技术要点介绍如下:
From 1990 to 1993, the Hunan Lingling aquatic product station undertook the scientific research project of “research on rice-fish high-yield model” issued by Hunan Science and Technology Commission. After four years of repeated practice and research, the “Taipa combined with fish farming,” a high-yielding pattern of rice fish. In 4 years a total of 4328 mu, 363.35 tons of fish, rice 4055.43 tons. Among them, the area of 1150.8 mu was implemented in 1993, 157.2 stewed fish were produced, 136.6 kg per mu; 1039.98 tons of rice were produced, 903.7 kg of mu per mu. Rice fish output value of 201.1 million yuan, mu of 1747.48 yuan, net income of 1.2942 million yuan, mu flat 1124.60 yuan, put into production ratio of 1: 2. 81. The end of 1993 has passed the provincial technical appraisal. The main technical points of the high-yielding pattern of rice and fish are as follows:
